Stage 3 Saph 4x4 Cossie

Just fitted with T35 turbo.

what boost do i run.

Car has all Stage 3 gear

 

23psi ish

 

What boost can i expect ?

I have seen stage 3 cossie same spec hit 350+

 

Do you mean a T34 (large turbo escos)

Have you fitted a new chip to suit the T34?

 

ya need a t34 chip for stage 3 otherwise ya gonna got rich lower revs and lean when ya come on boost, even if ya run the same amount of boost you are actually flowing more air

with a t34 and a propber chip between 22psi and 25psi ( mind im holding 26.5 psi , dont tell stu )

 

only 26.5psi?
you obviously want reliability
I run my T34's or 35's at 34 Peak and 30 held, everyone says the YB motor is unreliable so I will just help it on its way

 

on greens?

 

stus has told me to turn mine down as the spike of 27 holding just ober 25psi was makig the car run lean after 6grand under load in 4th and 5th

but the cars deicded to hold 26.5 psi , alot fookign stronger in 3rd 4th and 5th too


just hope stu dont read this

 

30psi held on greens is bit risky imo

 

no 30psi on greens is well well well well well lean, fuel presure will be jacked up soooooo high, dont even think ya could map it high revs under load in 4th and 5th at 30psi, it must tail off high revs

 

I would say your just waiting for the tick tick tick BOOOOM

 

or PING PING PING no more power, loads of smoke

 

in answer to your question, you run the bost that the chip is mapped for.

also as said above, amke sure the chip is for your exact spec (ie T34) or it will be a ticking time bomb

 

mines makes 290 at the wheels holding 21 on greens so thats mega safe..
i have a pro alloy cooler and breather tho..
hope this helps

 

b19bal,
sooo right, then you go and write.........

 

not really,,, whoever might of mapped it, might of not wrote the fuel load sites for 21

 

well its safe for my driving , also mine drops back down to 25.5 at 5200rpm in 4th and 5th

i never rag the car anyway and if i do im never at full throttle as im too scared and so rarley hold 26.5psi

was testing the other day and thats when i discovered it , i never do more that 130mph anyway and mostly i do between 90 to 100 to 105mph

so im safe , dont do racing either as i spend too much time looking at me rev counter to mnake sure im not over 6 grand

 

oh and soon as i swop jobs and get a decent income then its going on greys and getting a freshen up rebuild

 

ginge, you're not just ignorant to the facts, you're fookin arrogant aswell

 

forgot to mention the greys

 

jim my car aint melted at all and its been like it for 2 months now and i use it everyday aswell


cars melt when held, when have ya ever seen me hold my car on boost at all

 

glad ya said that


jim how is it arogant , my car my risk my choice

im sure the engine has problems already as it sounds like a diesel do to little ends

dont think 1PSI is gonna make a difference

 

Explains that boost then

 

sorry I have other things on my mind at the mo, didn't read the post properly and assumed max boost for a T34\5

 

oh yeah sorry ofcourse... i forgot about the fact that coz it aint melted yet that means its never gonna melt, im sorry i appologise

 

then thats ok, i accept , dont do it again

 

so what sort of boost is regarded as 'safe' on a cossie?

assuming that the engine internals are standard?
(as reguards rods etc)

on a T34/5 turbo that is
running say dark greens..

this would help me out too !
thanks!

 

its best to speak to a tuner and take his advice , all tuners have there own version of safe

 

ah i see!
whos the 'safest' tuner!? lol

 

stu , but then im biased , karl does the most impressive conversions for his customers for the specs though

but im very very very happy with the job stu done on my car and will only use him for my cars

 

if youre so happy, why are you not running a DIFFERENT boost level, and completely ignoring his advice

beleive it ot not al, actually do give 2 shits about you and your car and dont want to see the damn thing go wrong.

 

it wont trust me, im not as thick as i make out

i did worry at fist but its been fine and no miss fire ect so cant be doing worng
think about the conversation about power bands ect and my driving

remember i rarley take it to full boost and never rev it that high


it will be turned down when i can be assed though

 

gine, peak fuel is required at peak TORQUE

 

have faith,

oh and whats the WTFWTFWTFWTFWTFWFT thing ment to mean in ya avatar

 

who wrote the software in your ecu? thats the person you need to speak too! just because its running a stage three conversion dont mean it WILL be running 23psi,,,so its best to ask whoever tuned it

and by the way,, there isnt a safe boost,,,, not without checking fueling/det

 

its especially for you

 

ahmed bayjoo 330 chip in the car.

The boost limit is 27

 

its start by turning that down


where abouts ya from as im sure theres a good few tuners around that can help ya

 

I am not running 27psi,

I have been told the chip has fueling ect for 27psi.

Im in Peterborough. Harvey Gibbs said it seems fine but could do with a Pectal baby bord ?
